Other features of 4the invention will* be set forth in connection l'with the following detailed description of the illustrated einbodiment.v l i i l Referring pieliniinarily tov thegeneral features of the embodiment of the invention, illustrated by Way of examplein the accompanying drawings, a novel car engag-` also`wound, respectively over orabout two drums, one druni winding on the other drum u paying o in'one-directi-on, and operating y reversely in the opposite direction of travel Jincline. and to return idle and i'apidly after each car is so elevated to take upfthe next of the car propelling device. e

A single inotor drives both the drums, and a-clutch mechanism is provided which reverses the direction of rotation of the drums, Thisl clutch is preferably operated or controlled, either directly or indirectly, by the car propelling device reaching a certain place or point along the trackway andy Vthe device isthus rendered automatic to Asuccessively reverse the direction of travel of the car propellingdevice.

The relatively slowradvance movement, and the relatively quick returnon the' idle trip, ofthe device, are effected preferably through the gear ratios between the inotor and the respective drums. This is entirely practicable with'high speed on the return trip. due to the absence of load..

The tracks are arranged preferably with a very slight gradientpfor a long train of loaded cars whereby asingle car propelling device engaging the rear car will gradually progress or propel the entire train slowly forwardly, the foremost car being successively detached and/runV forward over the dump, and after beinguduinped and being run on to an=automatic switch which runs it,

'or thein, successively back` on the rempty tracks.

Thetravelvovf the carihaulV or propelling device on the emptyv track vis preferably relatively,- short, anditjinay be arrangedto elevate the cars one at'a time up a short succeeding cari, the tracks being inclined sufficiently to `perinitthe enipty carsto run therealong and be strung together ready to `be coupled into a train to return into the mine. y v Y Referring now in detail to the einbodiment of thel invention illustrated by way of example in the accompanying drawings, the

car hauling" and engaging" device will be first described. As `emloodied,'this device is adapted to run along a single rail, and. vthe device `and rail are sofconstrueted and arranged that the rail not only `supports' and guides the hauling device, but the haultherealong In this present illustrative embodiment, a rail 1 is pi'ovided,fwliich may be of ordinary 'I beam cioss-section,'and this rail may be laid down between the track rails, land may be spiked or otherwise' ifastenedtothe .y floor or ties 2 or othersupport forthetraclr" rails:

The car hauling Vdevice comprisesI ktwo plates and 4, vertically disposedfalongside,

and' extending'l upwardly fabovepthe 'sup- I,

portingvand guiciingrail I the greater part of their length theplates 3, and 4Q are spaced apart tol holdj or 'include between ytheni the wheels yor rollers upon-whichfthe ing device Visheld down in position at all* i times by the rail, while being free tofrun' eoY device runs and also to hold the car engag ,e

ing device'or dog.-r Atf'eachfend the plates 3 and 4C. are preferably bent inwardly with a double bentl'sothat they are in contact with eachother, asshown at 5 and 6in Fig.

3.y The hauling chainsor cables, or equivay lent device 7 may be fastened .into apertures 8 in the ends 5 and .6 of the hauling device.

As embodied,l the hauling, device is supported and progressed along the rail 1 by two rollers or wheels 9 ,and 10 l'ocatedre spectively, near either end of the device.

These rollers are yrotatably -mounted. on space ing sleeves vor bushings j11 and y12, y*respectively, againstthe ends'of which sleeves the plates 3' and 4 abut, "andare thus properly spaced apart. The sleeves 11"and`-12are centrally internally longitudiii allyapertured` f and bolts 13 and" 14:, respectively, vpass] throughy these apertures and through alined apertures in plates Stande. On bolts 13 yand 14 respectively are screwlthreaded nuts eaclrend ,of the device, :rollers 1*.7 and-18, located on the 'inner side of the plates 3 `and 4l, and proi jecting inwardly beneath the top li'aiige or i tread 19 of the rail 1. The rollers`17 and 18, respectively, are mounted uponv stub shafts 20 and 21, shouldered" so as tohold they rollers journaled vth'e`r"eon,"and they 1are also shouldered to pass through apertures in the plates 3 and ll, so that therollersare held in position wh'ilellceing free tov rotate.

Thefshafts 2O and 21 are screwthreaded on the rail.

Referring now to the yembodied form oitl car engaging device or dog, that is, the device supported upon the foregoing structure which engages with the car to propel it along the tracks movable and preferably pivoted dog 28 is provided, having an upwardly projecting part 29- adapted to engage with vsome part of the' car, such as a plate ekten'din'g downwardly fromy beneath the car bottom. The doglias a tail 30, which acts `as arestoring weight for the' rocking dog, as later 'describedw I The ldog 28' is pivotallyj mounted on a spacing sleeve 3l ez'iteiiding' crosswise between, and having its end :abutting Yon, the inner sides I. the platesg 'and 4i. `The sleeve 31 is internally centrally and longitudinally apertured -and ktherethrough passes a bolt which passes likewise through corresponding apertures in the plates 3 and at. The bolt iZtakes al nut the bolt thus serving to' hold the plates 3 and `l against the ends ot' the spacing sleeve 31, thus holdingv the platesv together properly spa-ced aparthand leaving the dog 2S tree to lpivot on the sleeve 3l.

constructed, the vdogtZS will rock 'from right to left in Fig'. Q to permit a car to pass going in the leit hand direction, as shown inv the dotted line' position otl41 ig.

i 2. The dog 28, howeverin vthe full line position of Fig. 2 is rigid against any' movement `to* the right hand about its pivot, so that it will push Vany car engaged by the dog onthe left hand side thereoic in the left hand directionl in Fig'. 2'. To facilitate acar passing the dog while traveling from right to left inl` ig. 2 the end 29 of the dog is provided with a rearv beveled face Sil, against which the car strike and thereby rock' the dog to the dotted. line position to permit the' car to pass, as already explained.

A. suitable stop to lii'iii't the; rocking movement of the dog in thisdirection is; provided by a bolt 35 passing through apertures in the'jplates 3 and 4 and zprovided with a nut 36. A. similar stop with which the' tailor' the dog is adapted to engage is provided at theother vside by a bolt 37 passing through they plates 3. and el', and provided with a nut 3SL The tailBO is weighted or is suiiiciently heavy to Yrestore the dog to then'fiill line positionv of Fig. 2 after the car has passed..A

In accordance With hertaiii features of inyentfion`,ithe cable yor chainlT 'inay driven inl vany suitable Amanner; or' by anyy suitable mechanism, but in accordance' 'wi-th* one-te'ature of tlie' -=invention, the cablel is wound slowly' in ythe carv hauling direction,

T, ...I- l t. land is returned yquicklyin theopposite di-y rection, and an embodiment of such driving V (Figs.7,

means" provided for the cable 8, 9i, llfa'd 13).

ln such embodied form, two' cables 'ofr like devices 7 arefprovided, one cablejbeing attached tofoneend of the haulingdevice fand 1winding upon' a drum, while another cable 7 is attached to the other end of the cart hauling device f and lsinliulaneouslyA funwinds `from va drum',.duringfthe car hauling movement inone direction, the winding and uiiwiiiding ofthe cables being reversedd'uringtl'iey travel of (the car hauling device inther opposite direction." ln the embodied torni,

twovdrum's are' employed, and incorporated therewith andV with `the driving mechanism there'iior is `the quick return.' feature 'for the car hauling*devicer 'onv its idle trip.- Y

- In Fig. 7 a train oi loaded cars' flyis shown on a trackl, in which track islocated a'car dump or t'ipple 47. ln this illustrated application of the invention vte -a mine', the mine month-is shown at 48, the

lloaded train, usuj ally' consisting of a large' number of loaded carsl, is-'hauled' out by a ,locomot-ivev or other suitable means, and is-lett upon the track 4:6, for the cars to be dumped singly and thenfto be switchedto another t'raclru andthen madeA u'p into/a train ot empty cars to be returned to the mine for'reloading. 'f

Asinle car hauling' device is' sufficient f for the entire train, the device engaging with some part of' thefrear or anyncar of the train,and 'pushing or' pulling",v or-both the entireltrain forward slowly. Y The leading ca-rs," o n`e by one are detached from the Vfront' of the train, are runv forward, andare dumped Y' over thevdumpyk or ,tipple 47, 'and then are runjback on to the empty track, preferably a.v suitably graded track provided with an automatic switch i9. The

torniy of such `aj switch and graded track ,farewell known. After all the carsin Athe train' have been dumped', the hauling device is returned toy or near the point in its path of tracknearest to the mine mouth ready to engage the rear car of a new trip'oi` train ofloaded cars.l v

Means are 'providedior guiding the' hauldevice and the vcables aro-und curves iii the track, andfor this purpose the plates 3 andll (Fig. 5) Yare provided at eitherend Vand on the inner sidesthereot with inwardly extending bearing lugs 50,' preterably with rounded points, A 'adapted to bear upon the tread orlangew .of the railrat either side thereof to preyent the devicelfrom; bind-ing or ein the' Curve of thema `suitable guidingpulleys 51 may be` provided at convenient points along the curved track for the cables 7.

` Referring now to theembodied form of driving means, a motor` is shown mounted on a bed 61. A beveled pinion 62 is iixed on the motor shaft. Beveled pinion 62 meshes withV a beveled pinion 63 loose on a shaft 64, which shaft is supported in lbearings 65 and 66 mounted upon the bed plate' 61. Fixed to beveled gear wheel 63 is a gear wheel 67, which meshes with a gear wheel 68. TWheel 68 is mounted loosely on a shaft 69 which vshaft is supported in bearings 70 and 71, mounted on the bed plate.

The beveled pinion 62 on the motor shaft meshes also with a beveled gear wheel 73, mounted loosely on shaft 64. Fixed .to beveled gear 73 is` a gear wheel 74, which meshes with a gear wheel 75 likewise loosely mounted on shaft 69. Fixed on shaft 69 to rotate therewith isa drum 77 which is located close to and atene side of the gear wheel 68. Also fixed to shaft 69, at the opposite side of gear wheel 75 and close thereto is a drum 78.

' Mounted on shaft 69 to rotate therewith while being slidable therealong, and located between gear wheels 68 and 75, is a double cone clutch 80, which is slidable along the shaft 69 to pass alternatively into driving` and engaging with either the gear wheel 68 or the gear wheel 75. Gear wheel V68 has ixed thereto on the side toward lthe clutch Y80 a clutch member 81, and gear wheel 75 has ixed theretoon the side toward the clutch 80 a clutch member 82, both clutch members 81 and 82 cooperating alternatively with the clutch 80.

The manner of operation of the mechanism just described is substantially as follows:

When the motor is rotating in a given direction, .gear wheels 67 and 74 are both rotated thereby, but in opposite directions, and consequently gear wheels 68 and 75 are likewise rotating in opposite directions, loose upon shaft 69. In Fig. 8 the clutch 80 is shown in neutral position, so that it is not in engagement with either of the driven gear wheels 68 or 75. If clutch 80 is moved into engagement with cooperating Vclutch member 81, the clutch 80 and both the drums 77 and 78 will be rotated in the same direction as the gear wheell 68, by reason oiC the clutch 80 being splined on shaft and the drums 77 and 78 both being keyed to the shaft 69. It the clutch 80 be moved from the neutral 'position of Fig.

.8 into engagement with the other cooperating clutch member 82, it will rotate' in the opposite direction, and will cause both the drums 77 and 78 to rotate in the same direction therewith by reason of the gear wheel connections to shaft 69 already explained.

By reason, of the difference in the gear ratios on two sides,`.gear wheel 68 will cause a relatively slow rotation of the drum, and gear wheel 75 will cause a relatively rapid rotation of the drum. The first. is adapted for the slow moving of the loaded cars and the latter is adapted for the q uick return of the idle car hauling device. 2 y

While the mechanism may be controlled manually,means are provided forits automatic actuation and control by the cars, or a single car at proper points along the track, or such control mayy be exercised byy the car hauling device itself.

Iny the. embodiment of such means shown in Fig. 11, the cable winding mechanism is reversed automatically by the hauling device 3 reaching a `certain or predetermined po-int in its travel. In saidembodiment theactuating means for the clutch 80 comprises a yoked lever, having arms 88 and 89`iixed on a shaft 90, pivotally mounted onthe bed Y n plate 61. The lever arm 89 is provided with a handle 91, by which theclutch may be operated by hand. p l

Pivoted to thev arm 89 is a link 92, which is pivoted at its other end to one arm 93 of a bell-crank lever, which lever is pivotally` i supported at 94 upon the bed of the machine. l

The other arm 95 of the bell crank lever has a pin and slot connection 96 with an intermediate point on a rod 97. Rod 97 at one end is pivotally connectedto a lever 98, which lever is -pivotally supported at `'99, and its tree end 100 is yarranged and positioned to be engaged by the hauling device 3.

At its other end the rod 97 is pivotally connected to a lever 101, which lever is pivotally supported at 102, its free end 103 being positioned and arranged to be engaged by the car hauling device at the opposite v end of its travel. By reason of the pin yand slot connection Aandoperating mechanism later' described, when the lhauling device 3 engages either one of the levers 98 or 101, the clutch 80 is thrown from engagement with either gear wheel 68 or the gear wheel 75 past its neutral point and into engagement with the other of said gear wheels, thereby reversing the direction of travel of the car hauling device 3. The mechanism of Fig. 11 is largely diagrammatic in character for the sake of clearness.

Means are provided asstated, :tor insuringv the sliding of the clutch past its neutral point when passing from engagement with one of the gear wheelsl 68 or 75 into engagement with the other. y As embodied, spring operated means are provided for this purpose. A form thereof is shown in Fig. 12, including a double beveled 'lug 104 which. is

fixed to thelever 98by-means of a screw i VSoription will suilioe .for both. Cooperating l on by a spring-110.
